Nah, it doesn't work because the developer doesn't want it to. EAC works really well on Linux, the developer just has to enable it, which takes literally less than 10 seconds.
All the developer needs to do is push a button to make EAC work. They're probably busy hotfixing the 1.0 but I'm sure it'll work soon, they are excluding all steam deck users by not pressing it
If it's that easy, why isn't there a mod or fix for people on Linux to do it themselves?
